ESP32 一些手册和批注
*Arduino IDE
*这个板子是带了LoRa的版本, 国外还有一个TTGo 有类似的ESP32 + LoRa这种组合
*如果不需要LoRa, 可以考虑ESP32 DevKit 或者PicoKit都可以
ESP32 Heltec Lora V2.1

WIFI
目的:
ESP32 创建 Access Point -> 手机/电脑 登陆进 IP地址 -> 输入路由器WIFI 用户名和密码
ESP32联网
ESP32 WiFiManager - Easy WiFi ProvisioningStop hard-coding WiFi credentials in your ESP32 & ESP8266 sketches - use WiFiManager instead! Change your wifi info, without recompiling.https://dronebotworkshop.com/wifimanager/我自己改写的代码,目前还是Private,未整理,有需要的私信我

Tryit Editor v3.7 this is the basic command on HTML to create a form with lable, textboxes and a button (edited)
Input Data on HTML Form ESP32/ESP8266 Web Server Arduino IDE | Random Nerd Tutorials this is how to integrate the html back to ESP32 to pass the value back in (edited)
上面的例子需要一个简单的UI, 需要HTML来写
Input Data on HTML Form ESP32/ESP8266 Web Server Arduino IDE | Random Nerd TutorialsLearn how to create an ESP32/ESP8266 web server with three input fields (HTML form) to pass values to your ESP using Arduino IDE. Then, you can use those values as variables in your code.https://randomnerdtutorials.com/esp32-esp8266-input-data-html-form/
BLE (低功耗蓝牙)
这个要注意BLE不是蓝牙(Classic)
如果快速搭建App 用Thunkable的话只可以用BLE,不支持Classic功能
一些库里本来写好的,可以直接调用
*在MURU项目里有用到(自己的项目,不开源)

ESP32 摄像头版本搭载的是OV2640 2MP的像素
但是Youtube里面有自己DIY改成OV5640升级成5MP的例子
